Description
The 422-23 has a 6-1/2 in inclined scale for 0-2 in H2O and continues on a vertical section up to 23 in H2O. Dwyer inclined-vertical manometers combine an inclined section for fine low-range reading with a vertical section for higher readings on one liquid-filled scale. Reading the gauge oil column needs no power, which makes these manometers a common primary reference for low air pressures. They are used in HVAC testing, air balancing and the checking of draft and low differential pressure gauges.
